Hi Ryan,
Thank you for your response.
Actually I intend to get the censor data of several county. For each county, I created a separate dbf file and combine the census data to shapefile for the county obtained from TIGER.
Now that all the polygons has the required census data, I want to merge all of them so that a single output will show the census information of different county.
When I merged using the polygon, my census data is not presented. So i decided to convert to a raster then merge the raster together. But as you can see, theres white lines at some portion.
What should be my next course of action? I want to remove those white lines.
THanks,
Bernard
